A. SNIB', OF ILION, NEW YORK, ASSIGNOR TO REMINGTON TYPEWRITER ACORPORATION OF NEW YORK.

TYPE-WRITING MACHINE.

7 '0 all whom it m'ay concern Be it known that I, Gnome A. Sam, 9.citizen of the United States, and resident of Ilion, in the countyofy'Herkimer and State of New York, have invented certain new and usefulImprovements in Type-Writing Machines, of which the following is aspeci-- fication. I

My present invention {relates primarily to ribbon =mechanism fortypewriting machines and its general object is to provide new andimprovedmechanism of the character specified. 1

:".1 its present embodiment provides a sup rt for the line gage and forthe lever or device which actuates the ribbon vibrator said supportbeing mounted '7 lengthwise beneath the platen. The platen independentlyof but shiftab le 'with the case shifting mechanism of the ma inethrough a yieldingconnection between the two and being arrested at theend of t e shift by a stop on the shifted element with which stop thesupport-is constantly engaged.

" 'The purpose of the construction is to insure a ,practically unvaryingextent of shift ing movement for the ribbon vibrator and 'for the linegage notwithstandin'gpossible variation, due to yielding case'shiftingparts. I v More specifically theconstruction is designed as animprovement on that disclosed in the application of John H. 'Barr,Serial No. 3,474, filed January 21,;11915, which has eventuated inPatent No. 1 ,153,668,'granted September 14, 1915.

To the above and other ends my invention consists in the features ofconstruction, combinations of devices and arrangements of partshereinafter described and particuburly pointed out in the claims.

In the accompanying drawings illustrating the preferred form of mypresent invention, Figure 1 is a side elevation, partly in section, of aRemington typewriting machine embodyipg my invention, parts of themachine being omitted.

' Referring to Figs. 1, 2 and 3 the; main frame of the machine is shownas'c'omprisinga base 1, posts 2 and a top plate 3 that .supports fixedguide rails 4 on which runs a carriage truck 5. A platen 6 is'mounted ina platen frame shiftably connected with the truck, the relativelymovable truck and frame together constituting a platen carriage. Theplaten frame comprises end. bars and a connecting cross bar 8 thatextends axle 6 bears in the end bars 7 and these end bars are pivotallyconnected by devices 9 with the truck 5. A roller1O journaled on thecross bar is adapted to run on aishift rail 11 that is supported byupright arms 12- a y the sides of the base. Collars 17 fixed to said rodoutside the levers 15 by set screws 18 preventthe levers from endwisedisplacement on said rod. Secured to the forward arms of the levers asby rivets 19 are the parallel vertical end portions of a U-shaped ailplate '20, the levers and bail thus providing a rigid frame which bearsloosely on the'rod 16 and is maintained in place by the collars 17Pivoted at 21 on the sides of the bail 20 are forwardly extending arms22, eachprovided with a shift key 23. Underlying and cooperative withthe rear portions of the arms 22 arethe free upwardly and outwardlycurving ends of a leaf spring 24 that is secured to the horizontalportion of the bail. 20. The construction provides a ,yieldingconnection between the" shift keys 23 and the levers15 that support theshift rail. The upward movement of the shift rail is limited by theusual stops 25 on the ends of the carriage truck, said stops actingthrough the carriage axle 6 to arrest'the shifted parts. Iniadditionstops are provided for positively arresting the arms 22,

said stops being in the form of adjustable screws 26 that are securedin-a stationary cross bar 27, said screws projecting upward into thepath of ,the arms 22. Counter-balancing springs'28 are connected attheir front ends to lateral pins 20 projecting outward from the uprightends (ifthebail 20, the rear ends of said springs having fixedanchorages 30. The left-hand shifting arm or lever 22 is.providcd withthe usual locking devices for retaining t platen in its a uppermost orshifted positio Said devices comprise a sprmg pressed arm 31 pivoted onthe left-hand arm 22 and provided \\'ltl1 ll key cap or button 3:2, thelower end of said arm terminating in a hook 33 which is adapted toengage with a fixed abutment 34 to .rock the shift frame down whenthe'key 32 is actuated. Printing key levers are provided with keys 36and are connected by links 37 with sub-levers 38, said sulnlevers inturn being connected by links 39 with front-strike type bars 40 mountedon hangers-ll secured to a stationary segment or support 42. A universalbar 43 underlies the key levers and is carried by arms H depending fromcrank arms 4'5 which project rearward from the transverse rockshaft 46having stationary end pivots. Projecting rearward frbm said rock shaftnear its anddle is an arni 47 which is connected by-a link 48 withcertain of the escapementdevices not hereinshown but which are'ofordinary Remington construction.

Ribbon spools 49 are supported one at each side of the machine below thetop plate on horizontal shafts 50 and a ribbon 51 is wound on saidspools and led upward therefrom through openings in the top: plate,thence inward over stationary gnidesfizz and throughguide openings inthehead or upper portions of a ribbon carrier or vibrator comprising a pairofparallel wire guide loops rising from aslotted body portion- 54, saidvibrator being arranged .about centrally between said stationary nationto feed the ribbon guides52. For turnin the spools in alterongitndinallyback and forth, means are provided which' operate on the shafts 50. Saidmeans comprise (as m the'Remmgton No. 10) beveled pinions 55 mounted onthe rear ends 'of said a shafts and adapted to mesh with beveleddrivingpinions 56 spaced apart ona ribriii'ge is drawn leftward under-.the pull of the spring drum; the driving shaft 57v will be turned,causing one or the other of the ribbon spools to turn and wind theribbon thereon, thus feeding the ribbon lon 'tudinally. Means preferablyof the usua Rembon driving shaft 57 which is connectedthrough constantlyengaged beveled pinions -58 and 59 with a spring dram 60, saiddrum beingconnected by. a strap 61 with anarm ()2- on the carriage truck 5. Whenthe car'- mgton construction are provided for moving the driving shaft57 back and forth endwise to cause the driving pinions 56 to cn gagealternately with the pinions 55, thus reversingthe direction of theribbon feed.

The lower end of the ribbon vibrator 53;

54 is pivotally connected at 63 to the hori-- zontally disposed arm 64of a bell crank lever (55 which, as appears clearly from Figs.

1,2, 4 and 5, further comprises an angularly disposed arm lib-and abrace (37. The arm the operating lever butmcans are provided forrendering them separately etfective at will to operate sald levers saidmeans comprising a rocking frame 75 pivoted onthe rod 70. the rocking'frame having a slotted head 7(tthrough which the actuators 71 and7:2"pass the downwaxally evtending arms of said frame being cbnneCtedbya cross-rod -77. it spool 78 lodae on the rod 77 is engaged bytheslotted up r end of an angular. plate 7!) which is ml nstably mounted onI the arm 47 by mcans-of two screws 80 and S1.

The

For mimeographing urposes the frame 7 5is also capable of adustment leftward to bring both actuators in theopening 76", thereby rendering the frame inoperativeon the actuatorswhen the type keys are'actuated. The slidable adjustments of the rockingframe and its cooperation with the actuators are explained more fully inthe Barr patent aforesaid.

The endw'ise shift of the frame 75 is accoma crank arm 87 fixed to arock shaft 88 having stationary bearings and provided with a fingerpiece 89 which maybe turned to adjust the frame 75. A pointer 90 on therock shaft 88 cooperates with stationary indicating marks 91 tofacilitate; these adjustments. Detent devices forqmaintaining-the frame75 [set-in adjusted positions comprise a spring plate .92, fixed .to theshaft 88- and having perforations 93 which cooperate with a stationarylug 94. The above described devices for variably actuating the operatinglever 65 presubs'tantially likethose described and a5 .clalmedin theBarr atent aforesaid except thatthejadjustable p ate 79 and itsassociate 'partsreplace a plain arm or plate found in the Barr constrction;

' Referring-to e novel means for mount- 4 0, ing andfshifting, theribbonoperating lever 65- to;;w'hichmeans my present invention'morerespee lly, relates, it will-be seen from FigS; j1,--2;\ and 5 thatthe pivotrod 68 of the'leve: 65 is mounted on a bail-like frame 95,:thisframe constituting a support-for Said frame'95 comprises a cross portion96 connecting two parallel, rearwardlyextending side portions 97 fromwhich extend 5 downward parallel extensions 98 while on thecross-portiohs extend inclined upward and forward two arms 99 connectedby a cross portion 100 having a downwardly pro- I jecting central ear101, said cross portion terminating at its ends in forwardly pro jectinglugs 102. The ear 101 carries a guide screw 10.3 which'cooperates with aslot in the body gortion 54-0f the vibrator, as best shown in ig. 7. Theframe 95' is mounted connected with the downward extensions 98 and inturn are pivoted on'the stationary support. The upper pair of links 104are 6'5 pivotally connected at 105 and at their rear plished by devices(Figs. land 2) comprising a link 86 which connects said frame withonsets of parallel links which are pivotally ends. to pivot pins 106 onthe side portions of abracket 107 shaped like an inverted U, whichbracket is secured by screws 108 to the under side of the top plate. Thelower links 109 are pivotally connected at their forward ends bylaterally projecting pivot pins 110.with the lower ends of theextensions 98 while the rear end portions of said links are pivoted at111 to the sides of the bracket 107. Back of thepivots 111 the links 109are connected by an integral cross portion or bar 112, the links 109 andthe cross bar 112 constituting a-rigid bail which has the effect .ofsynchronizing the movements of the links. Diagonal draw springs 113, oneat each .side, are hooked at their ends into grooves on the pins 106 and110; The tendencyiof the springs is constantly to lift or raise thesupporting fra,n1e 95 and the operating lever mounted thereon. A stud114 extends rearward from the cross bar 96 of the frame providing abearing for a hardened roller 115 This roller is maintained by thesprings 113 in constant contact with the horizontal lip or stop surface116 of a stop bar 117 that extends longitudinally of the frame bar 8 inrear thereof. The stop bar 117 is formed at its ends with vertical slots118 which receive screws 119 by which the bar 117 isfixed at its ends tothe platen frame. The SCIGWutLIld slot connection affords an up and downadjustment of the stop bar 117 and a variable setting of the stop or lip116 in respect to the platen frame. By securing the stop bar only at itsends to the platen frame bar 8 any distortion or variation in the framebar 8 due to stresses and strains to which it may be subjected haspractically no effect on thestop bar and its lip 116, the bottom face ofthe lip, atall times remaining substantially in in the samenormalrelationship with the platen in both case positions thereof, the

vibrator automatically following the shifting movements of the platen.It will be understood that in shifting from lower to upper case thesupport 95 moves upward bodily, carrying with it the operatin lever andvibrator-but that the actuators 71 and 72 will not be affected by theshifting movement. During said movement the links 73 and 74 swing upwardabout-their respective points of connection with said actuators 71 and72 as pivots. The shifted position of the,parts isishown in Fig. 6.

It will be observed thatthe: link motion by which the up and downmovement of the support 95 is controlled embddies at each end of saidsupport what maybe described. as adouble toggle, ne toggle comprisingthe link 161 and the extension 98 and the .other toggle comprising thelink 109 and the downwardly extending arm of the bracket 107. \Vhen inlower case )osition the to"- D When the platen is shifted, the-members.port for the line gage.

com prising each toggle approach nearer each other and consequentlyrequire less of a pull from the spring so that though the spring weakensas its ends approach nearer together, it nevertheless exertssubstantially the sa'mceti'ect on the toggles in upper case as in lowercase position. As a consequence of this compensatory arrangement thepres-- sure of the roller 115 on the lip 11(3 i s'maintainedsubstantially uniform at all times.

The points of connection ofthe spring 113 with the toggle or linkagedevices may, of course, be varied as found desirable. On releasing theshift key the platen carrier and ci'mnected parts will be restored tolower case position aslu sual and the lip 116 pressing down against theroller 115 will lower ease position the support 95 together with theoperating lever and ribbon vibrator.

The lugs 10: of the support 95am c0nfined loosely between parallelfingers 120 which are integral with and extend upward. Tumirward from aplate 121 fixed to the rear of the segment or support 12. These lingers120 cooperate with the lugs 102 toprerent sidewisc displacement of theframe' 95 during its up and down shifting movements, the fingers servingas guides for the frame. V

In addition to supporting the pivot rod as the. shiftable frame 95provides a sup'-* of ordinary constructiorv as illustrated in l igs. 2and 4 where it 1s designated by the reference numeral 122. The gage 1 sfixed to the front of the cross bar '96 by screws 123, a ,washer plate124 being interposed between the heads of the screws and the lowerportion of the line gage 122. By reason of its mounting on the shiftablesupport 95 the line gage is maintained in proper relationship with theprinting face of the platen in both lower and upper case, the upper edge122 of the gage proper indi eating or gaging accurately the bottom ofthe printing line in both case positions. v

1 Besides their guiding function in connection with the frame 95 thefingers 120 serve additionally to prevent the paper fingers carried bythe platen from ever getting in the path of the printing typebars. The

paper fingers are of ordinary construction and slidably mounted on asupporting This may be one means consisting that is,

each other-{that the. spring ends to the platen carrier and hav" zontalsurface, j'while the on t e sup 125 which extends lengthwise of theplaten above the printing line and is sup rted at its ends from the endbars 7. here are two paper fingers 126 of ordinary con-" struction, eachslidablyimounted on the rod 125 and extending upwardin front of theplaten )ast the printing line thereon, each paper finger carrying at itstop a roll 127 and having an outwardl which is provided with a {y ing'lip 128. The path of this lip is intercepted by the fingers 120 so thatif the endwise morement of the carriage is continued far enough the lip127 will contact with the off-set portion associate finger 120 andarrest the paper' finger 126, although the movement of the carriage maycontinue after such arrest, the

rod 125 sliding through the arrested paper finger. Therelationship'between the lip 128 and the inainportion'of the paperfinger is such that, as will be understood from Fig.

position of the stop bar and stop roller vary also in a direction atright angles to this first named direction, that is, in an up and downdirection, because of the case shifting operation; v

Various changes may be made without departing from-the spirit and scopeof my invention.
